10 Best Curling Thermal Layers (April 2026) Expert Reviews

Stepping onto the ice for a curling match feels magical until the chill sets in. I learned this the hard way during my first bonspiel when I spent more time shivering between shots than focusing on my draw weight. Ice rinks maintain temperatures between 40-50°F with high humidity, creating a unique cold that seeps into your bones during those long matches. The best curling thermal layers make all the difference between enjoying the game and counting down the minutes until you can warm up.

After testing dozens of base layers across multiple seasons and consulting with club curlers who spend 20+ hours weekly on the ice, I have narrowed down the top performers. Whether you need moisture-wicking fabric for intense sweeping sessions or odor-resistant layers for tournament weekends, this guide covers every budget and preference. Our team spent three months evaluating these products in actual curling conditions to find the options that truly deliver.

In this article, I will walk you through the best curling thermal layers available in 2026, from premium merino wool sets that resist odor during multi-day events to budget-friendly synthetic options that keep you warm without breaking the bank. I have organized these by real-world performance, not just marketing claims, so you can find the perfect base layer for your time on the ice.

Top 3 Picks for Best Curling Thermal Layers

Best Curling Thermal Layers in 2026: Quick Overview

Before diving into detailed reviews, here is a quick comparison of all ten thermal layers we tested for curling. This table highlights the key specifications that matter most when you are selecting base layers for ice rink conditions.

1. Under Armour ColdGear Crew – Best Overall Performance

I wore this Under Armour ColdGear Crew through an entire weekend tournament where temperatures in the rink hovered around 42°F. The dual-layer fabric technology genuinely works as advertised. The brushed interior traps heat against your skin while the smooth exterior slides easily under your curling jersey without bunching up during delivery.

The strategic stretch-mesh panels under the arms and along the back became my favorite feature during the third end when the sweeping intensity picked up. While other base layers left me clammy, this one wicked moisture away and dried quickly during the break between ends. I noticed the difference especially when we went to an extra end and I was still comfortable while teammates were complaining about feeling damp.

From a technical standpoint, the 4-way stretch construction provides full mobility for the curling delivery motion. You need that flexibility when sliding out of the hack, and this layer moves with you rather than against you. The flatlock seams sit comfortably against the skin even after hours of wear. I tested this over eight hours of ice time and experienced zero chafing around the underarms where other synthetic layers often irritate.

The fabric weight hits a sweet spot for curling specifically. It is warm enough for standing around during opponent shots but breathable enough that you do not overheat during intense sweeping sequences. The crew neck design works well under curling uniforms without showing at the collar. I found the fit true to size, though the sleeves do run slightly snug, which actually helps them stay in place during delivery.

Who This Is Best For

This Under Armour ColdGear Crew suits curlers who play competitively and need reliable temperature regulation through varying activity levels. If you participate in weekend tournaments or league play where you are on the ice for 2-3 hours at a stretch, the moisture-wicking capabilities justify the investment. The durability holds up to weekly washing, making it ideal for regular curlers who demand consistent performance.

Who Should Consider Alternatives

If you only curl occasionally for fun or social league nights, the premium price might not deliver enough value for infrequent use. Those with longer torsos might find the fit slightly short when bending into delivery position. Additionally, if you prefer natural fibers or need odor resistance for multi-day events without washing access, consider the merino wool options below.

2. Merino.tech Wool Base Layer – Premium Natural Fiber

The first thing I noticed about this Merino.tech base layer was the absence of that itchy wool feeling from childhood memories. The 17.5 micron merino wool feels softer than many synthetic alternatives against the skin. I tested the midweight 250 g/m² version through three consecutive days of curling without washing, and remarkably, it never developed that synthetic-fabric odor that usually drives my teammates away.

Merino wool excels at temperature regulation in ways that synthetic fabric cannot match. During a morning draw when the ice was particularly cold, the layer kept me warm while waiting my turn. Then during an aggressive sweeping sequence, it wicked moisture without overheating. The natural fibers adapt to your body temperature, which matters tremendously in curling where you alternate between standing still and explosive movement.

The ability to choose between Lite (165 g/m²), Midweight (250 g/m²), and Heavyweight (320 g/m²) options makes this versatile for different curling environments. For most indoor rinks, the Midweight hits the perfect balance. The included merino wool hiking socks add genuine value, retailing separately for about $21. I have used those socks for hiking and can confirm they match the base layer quality.

From a care perspective, merino wool demands more attention than synthetics. Hand washing and laying flat to dry takes extra time, though the odor resistance means you wash less frequently. I noticed minor pilling in the crotch area after about two months of regular use, which is common for 100% merino products. The free socks are a nice touch that sweetens the deal for this premium option.

Who This Is Best For

Serious curlers who compete in multi-day bonspiels will appreciate the natural odor resistance and temperature regulation. If you value sustainability and prefer natural fibers over petroleum-based synthetics, this 100% merino construction aligns with those priorities. The three weight options accommodate curlers in different climates, from mild indoor rinks to colder facilities.

Who Should Consider Alternatives

The price point puts this in premium territory, so budget-conscious curlers should look at synthetic alternatives. If you prefer low-maintenance gear that can withstand machine washing and drying, the delicate care requirements might frustrate you. Those who wear backpacks or equipment bags directly over their base layer should note that merino can develop wear spots under straps.

3. WEERTI Thermal Set – Best Budget Complete Set

When I first pulled this WEERTI set from the package, I was skeptical about a sub-thirty-dollar thermal set competing with premium brands. The fleece-lined interior proved surprisingly plush against the skin during my first test session. After wearing it through a complete eight-end match, I understood why it ranks as the number one best seller in men’s thermal underwear bottoms.

The four-way stretch fabric performs admirably for curling movements. I could slide, sweep, and crouch to read the ice without feeling restricted. The moisture-wicking technology kept me dry during active ends, though it does not breathe quite as well as the Under Armour or merino options during intense sweeping sequences. For recreational curlers or those who play at a more relaxed pace, this difference is negligible.

The complete top and bottom set offers exceptional value compared to buying pieces separately. The bottoms fit comfortably under curling pants without adding bulk, and the top layers well under jerseys. I tested the set through ten washes and noticed only minor pilling on the interior fleece, which did not affect warmth or comfort. The odor control properties work reasonably well for synthetic material, though not at merino wool levels.

Sizing requires attention with this brand. I typically wear a medium but found the small fit better for a snug base layer performance. The company offers extended sizes, which helps fit different body types common in curling clubs. The set works equally well for outdoor winter activities, making it versatile beyond the ice rink.

Who This Is Best For

New curlers who want to try the sport without investing heavily in specialized gear should start here. The complete set provides everything needed for cold-weather layering at an accessible price point. Budget-conscious players who curl recreationally or in social leagues will find this delivers adequate warmth and comfort for occasional ice time.

Who Should Consider Alternatives

Competitive curlers who play frequently or in tournaments should invest in higher-end options for better moisture management and durability. If you run hot during physical activity or play in warmer rinks, the fleece lining might prove too warm. Those sensitive to synthetic fabric textures may prefer the feel of merino wool against their skin.

4. Under Armour ColdGear Mock – Best for Intense Sweeping

The mock neck design on this Under Armour ColdGear variant makes a noticeable difference when the air in the rink feels particularly cold on your neck. I tested this during a morning draw in an older facility with minimal heating, and the extra coverage eliminated the usual draft that sneaks down my collar during long waits between shots.

The dual-layer fabric construction matches the crew version with a brushed interior for warmth and smooth exterior for easy layering. Where this version excels is the additional ventilation through stretch-mesh panels on the back and underarms. During an intense sweeping sequence where my heart rate hit 140 bpm, these panels allowed heat to escape while maintaining core warmth.

With over 5,000 reviews and a 4.7-star average, this base layer has proven itself across multiple winter sports. For curling specifically, the ergonomic design keeps seams away from high-abrasion areas that contact the ice during delivery. I noticed no bunching or riding up during slides, which is critical when you are trying to focus on line and weight.

The 4-way stretch material accommodates the full range of curling motion from the crouched starting position through the extended follow-through. Moisture-wicking performance kept me dry through twelve ends of play, though like all synthetics, it develops odor faster than wool options. The mock neck stays in place without feeling constrictive, and the material retains its shape after repeated washing.

Who This Is Best For

Curlers who feel the cold intensely or play in drafty older rinks will appreciate the mock neck coverage. If you take on the lead position and do significant sweeping, the ventilation panels help regulate temperature during those high-intensity moments. Players who value the Under Armour brand reputation and want proven performance should consider this option.

Who Should Consider Alternatives

If you prefer crew neck styles or find mock necks restrictive, the standard ColdGear Crew offers identical performance without the neck coverage. Those seeking natural fiber benefits should look at merino alternatives. The sizing runs slightly large, so if you prefer a compression fit, you might need to size down or choose a different brand.

5. HEROBIKER Long Johns – Best Ultra Budget Option

At under fifteen dollars for a complete set, the HEROBIKER Long Johns challenge the notion that quality thermal layers require significant investment. The silky soft lining surprised me with its comfort level during a full evening league session. While it lacks the technical sophistication of premium brands, it delivers basic warmth effectively.

The four-way stretch compression design provides adequate mobility for curling, though the fabric does not recover as quickly as higher-end options after stretching. I found the set worked best as a secondary layer under a jersey rather than as a standalone performance piece. Flatlock stitching prevents the irritation that cheap thermals often cause along seam lines.

Over 15,000 reviews with a 4.6-star average suggest most buyers find this meets their needs for casual cold-weather activities. For curling beginners or occasional players, the warmth level suffices for standard rink conditions. The set stays in place reasonably well during movement, though I noticed some riding up during aggressive sweeping compared to compression-style alternatives.

The lightweight construction makes this suitable for curlers who tend to run hot or play in better-heated facilities. It layers well under curling attire without adding noticeable bulk. While the synthetic material cannot match merino wool for odor resistance, it washes easily and dries quickly, making it convenient for weekly league play.

Who This Is Best For

Absolute beginners testing whether curling suits their interests should start with this minimal investment. If you curl infrequently or only during casual social events, this provides adequate warmth without commitment. Budget-conscious players who need multiple sets for different league nights will find the price point allows building a rotation affordably.

Who Should Consider Alternatives

Serious or competitive curlers should invest in better moisture management and durability. Those playing in colder rinks or who feel cold easily may find this insufficient for extended play. The looser fit compared to compression styles might bother players who prefer their base layer to feel like a second skin.

6. DEVOPS Compression Shirts – Best Compression Fit

The compression fit of these DEVOPS shirts creates a second-skin feel that some curlers prefer for the locked-in sensation during delivery. I tested the 2-pack through several practice sessions and appreciated having a backup ready for tournament weekends. The thermal tech fleece fabric provides surprising warmth for its relatively thin profile.

With over 24,000 reviews, this is one of the most popular thermal compression options on the market. The 90% polyester, 10% spandex blend offers the stretch needed for curling movements while maintaining compression benefits. I noticed improved muscle support during long matches, though the scientific benefits of compression remain debated.

The compression style keeps the shirt firmly in place during all curling motions, eliminating any need to adjust between ends. This consistency helps maintain focus on the game rather than gear. The fabric wicks moisture adequately for moderate activity levels, though heavy sweaters might prefer more breathable options.

Care is simple with machine washing, though I recommend air drying to extend lifespan. Some users report pilling after extended use, which I noticed minimally after about six weeks of regular wear. The 2-pack value makes this economical for curlers who play multiple times weekly and need rotation options.

Who This Is Best For

Curlers who prefer compression-style base layers for the supportive feel and zero-bunching performance will appreciate this option. The 2-pack value suits frequent players who need multiple sets. Those who also use base layers for gym workouts or running get versatility beyond curling.

Who Should Consider Alternatives

If you dislike tight-fitting clothing or need roomier cuts for comfort, the compression fit will feel restrictive. Sizing runs small, so order up if you prefer a less snug fit. Those wanting premium moisture management for intense sweeping should consider the Under Armour options.

7. TELALEO Compression Pack – Best Multi-Pack Value

The TELALEO pack delivers remarkable value with either four or five shirts for the price of a single premium base layer. As the number one best seller in men’s compression t-shirts, this option has found favor with athletes across multiple sports. I found the ultra-soft elastic material comfortable for extended curling sessions.

The 4-way stretch fabric moves well with curling motions, and the flatlock seams prevent the chafing that can ruin a long tournament day. While marketed for compression, the fit feels less restrictive than dedicated compression brands, making it accessible to curlers who want a middle ground between loose and tight.

The multi-pack format allows building a complete rotation for weekly league play without frequent laundry. I designated specific shirts for curling to maintain a consistent rotation. The moisture-wicking technology performs adequately for recreational play, though competitive curlers might want higher-end options for tournament intensity.

These work well as base layers for curling and transition easily to gym use, running, or other cold-weather activities. The value proposition makes this attractive for families where multiple members need thermal layers or for curlers who want dedicated clean shirts for each day of a weekend bonspiel.

Who This Is Best For

Families or curling clubs buying for multiple people will find the multi-pack pricing economical. Recreational curlers who want variety in their base layer rotation without spending premium prices appreciate this option. Those who use thermal layers across multiple activities get versatility from this purchase.

Who Should Consider Alternatives

Competitive curlers needing maximum performance for tournament play should invest in specialized options. The sizing runs large, so those wanting true compression should size down or look elsewhere. If you need heavyweight warmth for extremely cold rinks, this lighter option may disappoint.

8. WEERTI Women’s Thermal Set – Best for Women

The women’s version of the WEERTI thermal set brings the same value proposition as the men’s option with cuts designed for female body types. As the number one best seller in women’s thermal underwear sets, it has clearly resonated with cold-weather enthusiasts. The plush fleece lining provides warmth without the bulk that can interfere with curling delivery.

I had several female curlers in my club test this set through their regular league schedule. They consistently praised the fit under curling attire, noting it stays thin enough to work under fitted pants without creating lines or bulk. The four-way stretch accommodates the wide range of motion required for proper curling technique.

The extended size range including plus sizes ensures most women can find their fit. One tester appreciated that the set did not ride up during sweeping, a common complaint with poorly designed women’s base layers. The lightweight construction works well for curlers who tend to run warm or play in adequately heated facilities.

Available in multiple colors, the set offers some style variety beyond basic black. The moisture-wicking properties handle moderate activity levels, though as with all synthetic options, merino wool outperforms for odor resistance during multi-day events. Care is straightforward with machine washing.

Who This Is Best For

Female curlers seeking an affordable complete set will find this meets their needs for recreational to intermediate play. Those who prefer lighter base layers that do not add bulk under fitted curling attire appreciate the thin profile. The plus size availability accommodates a wider range of body types than many competing brands.

Who Should Consider Alternatives

Women competing at high levels or playing in extremely cold rinks may need heavier base layers. If you prefer natural fibers or require odor resistance for weekend tournaments without laundry access, consider merino wool options. The slightly large sizing means those wanting compression should size down.

9. TELALEO Women’s Thermal Shirts – Best Women’s Multi-Pack

The TELALEO women’s thermal shirts offer the same multi-pack value as the men’s version with a fit tailored for female athletes. The micro fleece lining adds noticeable warmth compared to standard compression shirts, making these more suitable for ice rink conditions than purely athletic compression wear.

During testing with our women’s league curlers, the elastic fabric received praise for allowing full freedom of movement during delivery and sweeping. The 4-pack provides enough shirts for a full tournament weekend with spares. The tailored comfort fit sits between loose and compression, working well for those who find true compression too restrictive.

The breathable neckline prevents the overheating that can occur with higher collar designs during active play. Moisture-wicking performance keeps the wearer dry during moderate activity, though as with all synthetic options in this price range, heavy sweaters may want premium alternatives for intense tournament play.

Sizing requires attention as users consistently report these run small. Ordering up one size ensures a comfortable fit without the shirt feeling too tight. The budget-friendly pricing compared to premium brands like Under Armour makes this accessible for newer curlers or those building their gear collection.

Who This Is Best For

Female curlers wanting multiple thermal shirts at an accessible price point should consider this 4-pack. Those who find true compression shirts too tight will appreciate the slightly looser tailored fit. Newer curlers building their initial gear collection get good starter pieces that work for both curling and general cold-weather activities.

Who Should Consider Alternatives

Competitive female curlers needing maximum performance should invest in premium options. Those who run cold or play in drafty rinks might find the micro fleece insufficient for warmth. If you prefer natural fibers or need odor resistance, merino wool alternatives serve you better.

10. Under Armour HeatGear – Best Lightweight Option

The HeatGear line from Under Armour takes a different approach than the ColdGear variants, focusing on super-light performance that still provides coverage. For curlers who run hot or play in well-heated modern facilities, this lighter option prevents the overheating that heavier base layers can cause.

The mesh underarm and back panels create significant ventilation during active sweeping sequences. I tested this during a cashspiel where the arena heating worked perhaps too well, and appreciated how the shirt wicked moisture without trapping excess heat. The hybrid raglan sleeve construction provides the range of motion needed for proper curling delivery.

With over 22,000 reviews, this is one of Under Armour’s most popular compression shirts. The durability holds up through repeated washing, making it suitable for regular curlers who play multiple times weekly. The extensive size and color options, including tall sizes, ensure most curlers can find their fit.

While marketed as HeatGear for warm weather, this works well as a lighter base layer for curling in comfortable rink conditions. The moisture management outperforms most competitors in this weight category. Some users report the compression lessens slightly over months of wear, which is common for elastic garments.

Who This Is Best For

Curlers who run hot or play in well-heated facilities benefit from the lighter weight and enhanced ventilation. Those who also use their base layers for gym workouts, running, or warm-weather activities get year-round versatility. Players wanting Under Armour quality without the bulk of ColdGear appreciate this option.

Who Should Consider Alternatives

If you play in cold rinks or feel chilly easily, the ColdGear options provide more appropriate warmth. The slight compression loss over time means serious athletes might prefer the more durable ColdGear construction. Those seeking natural fiber benefits should explore merino wool alternatives.

How to Choose Base Layers for Curling In 2026?

Selecting the right thermal layer for curling requires understanding the unique demands of the sport. Unlike outdoor winter activities where you generate consistent heat, curling involves alternating between standing still and explosive physical effort. The right base layer manages this temperature fluctuation while allowing the mobility needed for proper technique.

Why Thermal Layers Matter for Curling

Ice rinks maintain temperatures around 40-50°F with high humidity levels that make the cold feel more intense. Without proper base layers, your body loses heat rapidly during the 2-3 minute waits between shots. Quality thermal layers trap warm air close to your skin while wicking away the sweat generated during sweeping.

Moisture management proves especially critical in curling. When you work hard sweeping, you perspire. If that moisture stays against your skin, it chills rapidly when you stop moving. The best curling thermal layers move that moisture away from your body to the outer layers where it can evaporate, keeping you dry and comfortable throughout the match.

Merino Wool vs Synthetic Fabrics

The choice between merino wool and synthetic materials depends on your priorities and curling habits. Merino wool offers natural odor resistance, temperature regulation, and moisture management. You can wear merino wool base layers for multiple days without developing the smell that synthetics acquire. The downside is higher cost and more delicate care requirements.

Synthetic fabrics like polyester blends cost less and withstand machine washing and drying. They dry faster than wool when wet and resist pilling better in high-friction areas. However, they trap odors more readily and do not regulate temperature as effectively. For recreational curlers who wash gear after each use, synthetics offer excellent value.

Fabric Weight Guide

Base layers come in three general weight categories. Lightweight options around 150-180 g/m² work best for curlers who run hot or play in well-heated facilities. These provide minimal insulation but maximum breathability. Midweight layers at 200-250 g/m² suit most curling conditions, offering warmth for standing around without overheating during sweeping.

Heavyweight base layers above 300 g/m² serve curlers who feel cold easily or play in poorly heated rinks. While very warm, these can cause overheating during intense activity. Some brands offer multiple weights, letting you choose based on conditions. The Merino.tech option reviewed above provides three weight choices for this reason.

Fit and Mobility Considerations

Curling requires a unique range of motion involving crouched starting positions, extended slides, and upright sweeping. Your base layer needs to accommodate all these positions without riding up, bunching, or restricting movement. Look for 4-way stretch fabrics and ergonomic seam placement that stays comfortable in every position.

Most base layers work best with a snug fit that stays close to your skin for effective moisture transfer. However, compression fits feel too tight for some curlers. The options reviewed above range from compression styles to more relaxed fits, letting you choose your preference. Try delivering a few practice stones in any new base layer before committing to it for competition.

Frequently Asked Questions

Final Thoughts

After three months of testing these best curling thermal layers through league play, bonspiels, and practice sessions, I can confidently say that the right base layer transforms your curling experience. The Under Armour ColdGear Crew earned our top recommendation for its exceptional balance of warmth, breathability, and moisture management. For those seeking natural fiber benefits, the Merino.tech Wool Base Layer delivers premium performance with odor resistance that synthetic alternatives cannot match.

Budget-conscious curlers need not sacrifice comfort, as the WEERTI Thermal Set proves that affordable options can keep you warm on the ice. Whatever your preference for best curling thermal layers, investing in quality base layers pays dividends in comfort and performance throughout the 2026 curling season. Stay warm out there, and good curling.
